Experimental Study on Seed and Cutting Propagation of Tinospora sagittata
摘要
Abstract
[Objective]In order to further explore the artificial propagation and seedling cultivation technology of Tinospora sagitata,and effec-tively promote the protection and sustainable development and utilization of wild Tinospora sagitata resources.[Method]Using Tinospora sagit-tata seeds and vines collected in the Leigongshan Nature Reserve as experimental materials,a single factor experimental design was used to study the effects of different substrate types on seed germination and the effects of different substrate types,growth hormones,and concentrations on cutting propagation.[Result]The results showed that the highest seed germination rate(88.33±1.53)%was achieved when the sowing sub-strate was humus soil+river sand(1∶1);the highest survival rate(54.45±6.49)%was achieved when the cutting substrate was loam soil+river sand(1∶1);the highest survival rate(56.67±5.77)%was observed in cuttings treated with IAA solution at a concentration of 1.0 mg/L,the highest survival rate(75.56±8.39)%was observed in cuttings treated with NAA solution at a concentration of 1.0 mg/L,and the highest sur-vival rate(68.89±5.09)%was observed in cuttings treated with ABT solution at a concentration of 1.0 mg/L.[Conclusion]Based on the a-bove,the best germination effect of Tinospora sagitta seeds can be achieved by using humus soil+river sand(1∶1)as the sowing substrate,which can be used as the substrate for Tinospora sagitta seeding and seedling cultivation;the optimal cutting effect is achieved with a mixture of loam soil and river sand(1∶1)as the cutting substrate;from the perspective of three different growth hormone treatments,the survival rate of Tinospora sagittata cuttings was improved to varying degrees.The highest survival rate(75.56±8.39)%was observed in the NAA solution at a concentration of 1.0 mg/L,indicating the best overall cutting effect.关键词
